Embodiment Construction

[0033] figure 1 It is a block diagram illustrating an aspect in which the numerical control device of the present invention stores the information of the operation history when the route table is operated.

[0034] When the numerical control device performs the path table operation, in each specified sampling period, the date and time information 30, the reference signal of the path table operation (time, spindle position, other axis positions, etc., value changes) are stored in the buffer 34. information) information 31, control data 32 controlled synchronously with the reference signal, and information 33 indicating the state of the numerical controller at the time of sampling.

[0035]The reference signal information 31 of the route table operation includes a signal indicating time, or a signal indicating the position of a specific axis of movement, or the position of a main axis, or the like. Furthermore, the position of the control axis controlled synchronously and the ...

Abstract

During path table operation, date and time information at sampling, the value of the reference signal, the position of an axis controlled in synchronization with the reference signal, and information on the state of the numerical controller are stored, for each predetermined sampling cycle, in buffer as operating history information. The operating history information stored in buffer is then transferred in operating history saving memory when an alarm is generated, and then displayed on a display device. By displaying operating history in this way, the location of the data instructed in path table operation, the state of the numerical controller and the position of the control axis when an alarm is generated can be specified.

Description

technical field [0001] The present invention relates to a numerical controller for controlling the operation of a path table. Background technique [0002] Set the signal of the value change of time, spindle position, other axis position, etc. as a reference signal, and store the position of the control axis corresponding to the value of the reference signal set as tabular data, synchronously with the reference signal The control method of the drive control control axis is known as path table operation. [0003] For example, JP-A No. 2003-303005 describes that the position of the control axis relative to the reference axis (reference signal) is stored in a data table, and a path table that drives the control axis synchronously with respect to the movement of the reference axis is described. During the operation of the path table, the auxiliary function or the main axis function is set and stored for the position of the reference axis, and the auxiliary function or the main ...
